Yup's Review of Matador Arms Mag-X Conversion Caliber
This Magazine adapter fit perfectly. Tried it in an older and newer PSA AR-15 mag well as well as my Aero lower. All of which fit perfectly. The Aero was a little more snug than the PSAs but I had no issues with the fit and function of the 15, 17, and 21 round P320 mags that I have. All Sig made mags. I’d assume they’d work with the cheaper mags as well.
Pros:
- EASY INSTALL
- accepts all sig made mags
- worked with several different lowers
Cons:
- None
Best Used for:
- AR-9 build that doesnt require a dedicated 9mm lower
Would Recommend:
Yes
